(2000)
Sodium telluride (Na2Te), obtained in situ by borohydride reduction of elemental tellurium, reacts with 2-(2-bromoethyl)-1,3-
dioxane resulting in bis(2-{1,3-dioxan-2-yl}ethyl) telluride (L), which is isolated as an unstable ...
1,8-Dihydroxyanthraquinone anchored on silica gel: synthesis and application as solid phase extractant for lead(II), zinc(II) and cadmium(II) prior to their determination by flame atomic absorption spectrometry
(2002)
A new chelating matrix has been prepared by immobilizing 1,8-dihydroxyanthraquinone (DHAQ) on silica gel modified with (3-aminopropyl)triethoxysilane. After characterizing the matrix with thermogravimetric analysis (TGA), ...
Preconcentration of lead with amberlite XAD-2 and amberlite XAD-7 based chelating resins for its determination by flame atomic absorption spectrometry
(2002)
Four chelating matrices prepared by coupling Amberlite XAD-2 with chromotropic acid (AXAD-2-CA or 1), pyrocatechol (AXAD-2-PC or 2) and thiosalicylic acid (AXAD-2-TSA or 3) through azo spacer and impregnation of Amberlite ...
